It would be cool if they make battery filling all of space inside that replacement back cover, thus battery not sticking as square from space designed for original battery, and battery could easly be 2500+ mAh....

Same here. My kit arrived today from Nicecans. Was a bit concerned after reading the negative reviews going around, but my order has been fulfilled. Fits great & phone feels better to hold. Time will tell how the battery performs.

This cover fits perfectly. So snug you sometimes forget you have a cover on.

Hello guys, just got the extended battery, put it in the phone (switched off) and charged it up overnight.
battery calibrated after booting and will now test. But now im worried i calibrated it "to late", meaning i should have done it before charging the battery. any thoughts?

I'm really happy with the performance of Samsung extended battery kit so far. Phone usually lasted only half day for me but with this new kit I could have my phone standy all day without having to charge it once
